2 Claims. (Cl. 86-31) (Granted under the act or March 3, 1 883, as

amended April 39, 1928; 379 G 757) I The invention described herein maybe manufactured and used by or for the Government for governmentalpurposes, without the payment to me or any royalty thereon.

This invention relates to apparatus for filling an explosive containerwith explosive and forming the booster cavity or fuse well therein.

It is an object of the invention to provide an exceedingly simple andsafe apparatus for filling containers with explosives, such as shellsand bombs, that is adapted to accomplish both the filling and booster orfuse well forming steps in one operation instead of the usual twooperations employed to attain this result as generally practiced in theart.

The specific nature of the invention as well as other objects andadvantages thereof will clearly appear from a description or a preferredembodiment as shown in the accompanying drawing in which:

The single view constituting the drawing shows in longitudinal sectionthe filling apparatus or this invention as used in filling an explosiveshell.

Referring to the drawing by characters oi reference there is shown inlongitudinal section one conventional type oi high explosive containerindicated at 58 with the fuse well or booster cavity forming pour funnelof this invention also shown in longitudinal section and disposed inoperative filling and fuse well or booster cavity forming relation withrespect to the container to as generally indicated at H. While the formof the container l is herein shown to be a shell it will of course beobvious that the adaptation of the funnel is not limited to anyparticular container, but may be used in filling any explosivescontainer where a fuse well or booster cavity is desired.

The funnel ll comprises a cylindrical tubular adapter portion 12provided at its lower end portion with an outwardly extending annularflange l3 adapted to be received within the mouth of the shell orcontainer ID in close proximity to the interior walls of the containerand a. funnel portion l4 suitably secured to the upper end portion ofthe cylindrical adapter portion in any desired manner to form theannular seat IS.

The lower ends or the tubular adapter portion l2 and annular flange I3are disposed in substantially the same horizontal plane and a suitablescreen I6 is secured thereover for a purpose hereinafter made apparent.

The depth of the adapter portion R from the seat IE to the screen Itwill vary with the depth of the fuse well or booster cavity desired.

In the operation of filling a shell or other container with explosivesthe funnel H i arrangedwith its adapter portion i2 disposed within themouth of the container at in supported relation by interengagement ofthe nose of the container and seat 55 of the funnel as shown in thedrawing. With the funnel it and container to at room temperature, moltenexplosive, such as TNT, is poured within the container through thefunnel and freezes in the plane of the lower end of flange i3 asindicated at El thu preventing the explosive from entering the spacebetween the exterior of the tubular portion it of the funnel andadjacent portion or the interior wall of the container, which keeps thethreads and other machined surface within this space booster cavity asnow extensively practiced in v the art will be wholly eliminated.

Having now described what is at present considered a preferredembodiment of the invention I claim:

1. In a fuse well or booster cavity forming pour funnel in combination,an adapter portion provided with an outwardly extending flange at itslower end, a funnel portion secured to the upper end of the adapterportion forming an exterior seat adjacent the junction thereof, and ascreen secured across the lower ends of the flange and adapter portion.

2. In a. fuse well or booster cavity forming pour tunnel -incombination, a cylindrical tubular adapter portion provided with anoutwardly extending annular flange at its lower end, a. funnel portionsecured to the upper end of the adapter portion forming an annularexterior seat adjacent the Junction thereof, and a. screen securedacross the lower face of said flange and adapter portion.
